Based on Erik Max's suggestions:
import sys, time
def output(char):
sys.stdout.write(char)
sys.stdout.flush()
def spinner(rotations, interval):
symbols = '|/-\\'
for x in xrange(rotations):
for ch in symbols:
output(ch + '\b')
time.sleep(interval)
output(' \n')
if __name__ == '__main__':
spinner(int(sys.argv[1]), float(sys.argv[2]))
c:\> python spins.py 55 .05
(outputs |/-\ etc....)
